Purple Gold has passed a gold purity analysis for the first time conducted by the Japanese Mint, which manufactures Japan's coins.
Purple Gold was graded with the "Hallmark" designation as a proof of its gold purity from January 2022. We are very happy to announce that the world's first 18K Purple Gold coin is now available in Japan. The coins are with the engraving of the Japan Mint.
